At the time of his tragic death in February 2013, former Navy SEAL Chris Kyle, the most accomplished sniper in U.S. military history, was finishing a remarkable book that retold American history through the lens of a hand-selected list of firearms. Kyle masterfully argues that guns have played a fascinating, indispensable, and often under-appreciated role in our national story. Kyle carefully chose ten guns to help tell his story, including the American long rifle, Colt .45 revolver, Winchester rifle, .38 police handgun, and the M-16 rifle platform Kyle himself used as a SEAL. This is also the story of how American innovation, creativity, and industrial genius has constantly pushed technology—and U.S. power—forward.
